I am so sorry. Can you call your pdoc and ask if there is anything you can do to help? I don't think it is a good idea to take something prn unless your doc prescribes it that way.

Do you drink coffee? Make a huge pot of it and down it.

What is it you are reading? That is a lot to read. Is it interesting or pretty boring?

I wonder if you can ask at the school you are attending if they have a copy of that book/chapter/whatever on audiotape or something? Seems like they should to accommodate students who cannot see well, maybe even for dyslexia. BP is a recognized federal disability too. If they have it, maybe an audiobook would be the way to go. Doesn't hurt to ask.
